Definition<\/strong><\/p>\n<\/td>\n<\/tr>\n A nanomaterial can be defined as a material in which one or more of its dimensions is between 1 or 100 nanometres. We are mainly concerned here with engineered nanomaterials, which are materials in the nanoscale that have been purposefully manufactured to have that size with the intention of it having certain properties.<\/p>\n Nanostructure <\/strong><\/p>\n A nanostructure is a structure with at least one dimension in the range of 1 to 100 nanometres. Examples can include a 1 dimensional nanostructure (such as a nanotextured surface), a 2 dimensional nanostructure where it has two dimensions at the nanoscale (such as a carbon nanotube) or a 3 dimensional structure, with all 3 dimensions at the nanoscale (such as a nanoparticle).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n A wide variety of nanomaterials can be used within the energy sector, with their potential uses depending upon the functionality and physical properties of the material. Obviously, some materials can be used as they are electrically conductive, whilst others will be used for their strength or durability. Some materials have multiple properties that can be useful. Nanomaterials are often used in conjunction with other materials, many of which will be non-nano in size, and are used to provide added functionality. Thus, a nanomaterial may be added into a composite material to make it electrically conductive, or because it provides more strength or makes it more insulative. There is such a wide variety of nanomaterials that can be used it is impossible here to list them all, so a few illustrative examples will be given to show how some nanomaterials could be used within the energy sector.<\/p>\n Graphene:<\/strong> A very thin layer of carbon that is described as a 2D material, as it can be a large molecule measured in one direction, whilst still being only one atom thick. Often described as the world\u2019s thinnest material, graphene is also one of the world\u2019s strongest materials, as well as being electrically conductive. It is its interesting physical properties that make graphene a candidate for many different applications, including in the energy sector. It has been suggested that batteries made using graphene could be flexible and light, whilst also being able to charge quicker and for them to hold power for longer. As well as b<\/p>\n eing light and strong, graphene has a high surface area which allows it to store more energy, making it an ideal candidate material for use in energy storage.<\/p>\n Carbon nanotubes:<\/strong> A rolled up cylindrical sheet of carbon atoms which are either single walled (one rolled sheet) or multi-walled (cylinders of carbon within other cylinders of carbon), carbon nanotubes (CNTs) have unique and interesting properties. The functional properties of different CNTs depend upon their different physical properties, such as diameter, length, or chirality (twist). They are one of the stiffest and strongest materials that can be made, far stronger than steel for example, but are also light in weight. These properties make them ideal for use in strengthening composite materials, such as those used in the blades of wind turbines, where they can add strength. CNTs are also a great potential material for use in energy storage, where they can be used to replace the graphite electrodes in rechargeable lithium-ion batteries. As they can be made thinner and lighter and are also highly conductive, CNTs could allow batteries to be made much lighter, which is useful in areas such as vehicle batteries.<\/p>\n Silver nanoparticles<\/strong> Silver does not seem an obvious material to use in energy generation or storage due to the high cost of the material. However, at the nanoscale a small amount of material can go a long way! Silver nanoparticles, also known as AgNPs, have very high electrical conductivity. The electrical conductivity of silver is 6.30×107<\/sup>m\/ohm, in comparison with copper at 5.96×107<\/sup> m\/ohm, making silver a better conductor. This makes it ideal for use in printed electronics, where it can be added to inks to create conductive inks. Inks with AgNPs in their mix have been considered for use in solar panels, where being able to print panels rather than manufacture them using the traditional photolithography, would speed up the rate and reduce the cost of manufacture.<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":{"_vibebp_attr":"","_vibebp_dimensions":"","_vibebp_responsive_height":"","_vibebp_accordion_ie_support":"","footnotes":""},"module-tag":[],"class_list":["post-1446","unit","type-unit","status-publish","format-standard","hentry"],"_links":{"self":[{"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/unit\/1446","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/unit"}],"about":[{"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/types\/unit"}],"author":[{"embeddable":true,"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/comments?post=1446"}],"version-history":[{"count":1,"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/unit\/1446\/revisions"}],"predecessor-version":[{"id":1468,"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/unit\/1446\/revisions\/1468"}],"wp:attachment":[{"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/media?parent=1446"}],"wp:term":[{"taxonomy":"module-tag","embeddable":true,"href":"https:\/\/lms.nanoproject.eu\/lms\/wp-json\/wp\/v2\/module-tag?post=1446"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n Nanomaterial<\/strong><\/p>\n ![\"\"](\"https:\/\/lms.nanoproject.eu\/lms\/wp-content\/uploads\/2022\/01\/graphene-161771_1280-768x1209.png\")
